Range of biquadratic and triquadratic Heisenberg effective couplings deduced from multiorbital Hubbard models
Rahul Soni, Nitin Kaushal, Cengiz Şen +3
We studied a multi-orbital Hubbard model at half-filling for two and three orbitals per site on a two-site cluster via full exact diagonalization, in a wide range for the onsite re…
Multitude of Topological Phase Transitions in Bipartite Dice and Lieb Lattices with Interacting Electrons and Rashba Coupling
Rahul Soni, Amit Bikram Sanyal, Nitin Kaushal +3
We report the results of a Hartree-Fock study applied to interacting electrons moving in two different bipartite lattices: the dice and the Lieb lattices, at half-filling. Both lat…
Intertwined charge, spin, and pairing orders in doped iron ladders
Bradraj Pandey, Rahul Soni, Ling-Fang Lin +2
Motivated by recent experimental progress on iron-based ladder compounds, we study the doped two-orbital Hubbard model for the two-leg ladder BaFeS. The model is constructe…
Investigation of strut-ramp injector in a Scramjet combustor: effect of strut geometry, fuel and jet diameter on mixing characteristics
Rahul Kumar Soni, Ashoke De
The strut based injector has been found to be one of the most promising injector designs for supersonic combustor, offering en-hanced mixing of fuel and air. The mixing and flow fi…
Modal Decomposition of Turbulent Supersonic Cavity
Rahul Kumar Soni, Nitish Arya, Ashoke De
Self-sustained oscillation in Mach 3 supersonic cavity with a length-to-depth ratio of 3 is investigated using wall modeled Large Eddy Simulation (LES) methodology for ReD = 3.39*1…
Role of Jet Spacing and Strut Geometry on the formation of Large Scale Structures & Mixing Characteristics
Rahul Kumar Soni, Ashoke De
The present study primarily focuses on the effect of jet spacing and strut geometry on the evolution and structure of the large-scale vortices which play a key role in mixing chara…
Investigation of Mixing Characteristics in Strut Injectors using Modal Decomposition
Rahul Kumar Soni, Ashoke De
Effect of large-scale vortical structure on mixing and spreading of shear layer is numerically investigated. Two strut configurations namely Straight & Tapered strut at two convect…
